WebJun 29, 2012 · A gate last process may be implemented to address the concerns of high temperature processing on metal materials. In a gate last process, a dummy poly gate is initially formed and processing may continue until deposition of an interlayer dielectric (ILD). The dummy poly gate may then be removed and replaced with a metal gate. Webperformance, gate electrodes were formed by deposition of a thin TiN electrode followed by amorphous Si deposited in a CVD RTP chamber. The wafers were completed through metal contact to source-drain and gate by a typical self-aligned gate process flow. SiO2 controls were also processed through a standard flow from ISSG deposition.

WebThe main points are discussed below. (a) the poly-silicon work function is increased from a near ideal value of 4.17eV achieved using in-situ poly doping to a more typical value of approximately 4.3 to 4.4eV for implanted/P+ compensated poly gates. (b) the poly can become depleted during normal device operation.

http://www.cityu.edu.hk/phy/appkchu/AP6120/7.PDF WebThese simulations show the importance of not defining the poly gate itself as the electrode when simulating MOSFETs. This would instruct the simulator to treat the poly-gate as a perfect conductor which would by definition not deplete. The accurate approach is to deposit metal onto the poly and define this metal layer as the electrode.
